A CBS investigation has revealed that parking tickets stemming from 85% of the parking meters in Philadelphia are invalid. Pennsylvania law requires inspectors to certify each parking meter for accuracy once every three years, but the single inspector working for Philly’s Licenses and Inspections Department, the city agency in change of certification, has visited less than 15% of all parking meters—but he has found the time to certify some meters 8 times while others go completely unchecked. As a result, thousands of parking tickets are invalid under state law.
